| titleOfInvention | A kind of restorative procedure that pollution of chromium underground water is repaired with calcium polysulfide |
| abstract | Purposes and restorative procedure of a kind of calcium polysulfide in chromium-polluted soil or groundwater remediation, pollution of chromium reparation is carried out using calcium polysulfide, and in particular to two kinds of restorative procedures：The restorative procedure of chromium-polluted soil is repaired with calcium polysulfide；Investigated including soil Cr pollution level, prepare calcium polysulfide aqua, determine adding ratio, adding calcium polysulfide aqua, keep the skin wet, repair reaction, soil maintenance and soil property regulation after reparation for calcium polysulfide aqua；The restorative procedure of pollution of chromium underground water is repaired with calcium polysulfide, including arranging decanting point and determination reparation pharmaceutical quantities, preparing reparation medicament, injection point location, the injection of calcium polysulfide reparation medicament and adjusting decanting point position and decanting point quantity etc..Operating process of the present invention is simple, medicament steady sources, reaction speed are fast, repairing effect is good, repair after the advantage such as can maintain a long-term stability, can be used in extensive implementation, economical rationality is the recovery technique of a kind of comparatively ideal chromium-polluted soil or underground water. |
